Be it known that I, WILLIA A. TNsALLs, a citizen of the United States, residing at Omaha, in the county of Douglas and State; of Nebraska, have invented certain newand' useful Improvements in Wrenches, of which the following is a specification.

This invention relates to combination tools and more particularly to wrenches.

One of the objects of this invention resldes in the provision of a wrench conslstlngof a certain embodiment of elements forretaming the blade of a screw driver in fixed relation with the handle of the wrench.

Another object of this invention resides in the provision of a wrench havmg adjustable jaws for engaging different slzes of nuts and retaining the blade of a screwdriver in rigid position on the handle of the wrench.

With these and other objects in View, this invention resides in certain novel features of construction and arrangement of elements to be more particularly set forth in the specification herewith and pointed out in the appended claims, it being understood that the right is reserved to resort to such changes in detail as come within the scope of the claims.

In the accompanying drawing Figure 1 is a side view of a wrench as constructed in accordance with this invention;

Fig. 2 is a sectional view approximately on line 2-2 of Fig. 1;

Fig. 3 is a detail perspective view of a screw-driver blade;

Fig. at is a detail perspective view of the jaws in juxtaposition;

Fig. 5 is a detail perspective view of the slidable collar.

Fig. 6 is a detail perspective View of a portion of the wrench handle in juxtaposition with the cap plate.

In the present embodiment of this invention, the numeral 5 designates the handle of the wrench which is preferably of skeleton construction and is provided with sockets 6 for the accommodation of the grooved heads 7 of the jaws 8.

The aforesaid jaws are pivotally retained in the sockets 6 by a housing 9 which is secured to the handle by screws 10 and 11, the former of which pass through the heads of the jaws to form trunnions therefor. These jaws are provided with lips 12 which project inwardly and they have angular-131 dispos edfinner surfaces forengagement'with nuts or the shank 13 of the screw-driver blade 1 1 when arranged operative positip ,The bodyportions of these jawsare dir ot'ed outwardly from their heads 7 and their nut engaging portions are disposed substantially in alinement with the handle 5. Adapted to slidably engage the jaws is a collar 17 including the parallel extending sides 15 havinga centrally disposed apertured rib 16 for engaging the inner surfaces of the body portions of the jaws to cause them to spread during the retraction of the collar and through the engagement of the ends of the collar with the outer surfaces of the jaws, they are caused to close as the collar is moved outwardly. The extended sides 15 of the collar are provided to prevent the twisting action of the jaws during 7 the operation of the wrench.

In order to slide the aforesaid collar outwardly and inwardly, a threaded bolt 18 is engaged in the aperture of the rib 16 and is directed inwardly between the grooved heads 7 of the jaws and through the apertured walls 19 and 19 of the cap plate and handle. Between the walls 19 and 19' of the cap plate and handle is disposed a rotatable nut 20 for engagement with the threaded portion of the bolt 18.

The cap plate is provided with the ends 22 which fit against the faces of the ends 23 of the handle.

This wrench is readily adapted to be used 0 on various sizes of nuts and its adjustment is accomplished by rotating the nut 20 pivotally held to said sockets, a collar slidably surrounding said jaws, an aperture being formed below said sockets, a centrally apertured rib carried by the collar and hearing on the inner sides of the jaws, a threaded bolt secured at one end to a rib of the collar and extending inwardly therefrom, spaced walls formed on the handle adjacent the sockets thereinand having semi-circular apertures arranged to guide said bolt, and j a nut carried by the threaded end of the bolt.

2. The combination with a handle having substantially semi-circular sockets adjacent its outer end, of jaws having their inner ends formed to rotate in the sockets of. the handle, a collar slidably surrounding said jaws, a centrally apertured rib carried by the collar and bearing on the inner sides of nut carried by the threaded end of the bolt between the spaced walls of the handle, a cap plate over the jaws and bolt, spaced walls formed on the inner surface of the cap plate and having semi-circular apertures therein, in alinement with the apertures in the walls of the handle and trunnions securing the forward end of the cap plate over the pivoted ends of the jaws.

In testimony whereof I aflix my signature.

WILLIAM A. INGALLS.
